MB5TH 5-channel SHT10/11/20/21 temperature and humidity acquisition block Software acquisition interface

Chapter One Product introduction
overview
MB5TH 5-channel SHT10/11/20/21 temperature acquisition module can collect 5 SENSIRION Swiss SHT10/11 temperature and humidity sensors, which has high temperature accuracy and good consistency;Temperature and humidity signal data collected by the module is output through the RS485 interface.The module adopts ModbusRTU communication, which can be adapted to PLC, man-machine screen, DCS and various configuration software.The module updates the online status of the sensor in real time.Through the corresponding register status query, the online status of the five external SHT10/11/20/21 sensors can be monitored in real time.It can be used for cold storage temperature data collection, vegetable greenhouses, animal breeding, industrial environment monitoring, granary temperature monitoring, egg hatching, medical refrigeration and other environmental temperature data collection and control.
And.Characteristics
1.High-speed collection of Swiss (SENSIRION) SHT10/11/20/21 Temperature and humidity sensors, good real-time temperature monitoring.
2.Real-time monitoring of the SHT10/11/20/21 online status of the sensor facilitates on-site troubleshooting and fault location.
The 3.5-bit digital tube display displays the real-time temperature and humidity values of each channel in rotation, which is convenient to view the real-time temperature and humidity on site.
4.Adopt the standard Modbus-RTU protocol, which can be adapted to PLC, man-machine screen, DCS and a variety of configuration software.
5.Communication protection: Isolated RS485 communication, signal output port adopts overvoltage and overcurrent protection.
6.Power supply polarity protection.Strong and big

V. Module indicator and switch function description

1.POW/SET; Module working status indication

A.Green light is on: the module is working in running state. B.Red light is on: the module has configuration parameters have been written, need to re-power.2.

2.TXD/RXD: Communication status indication

A.Green light is flashing: communication received data B.Red light is flashing: module is sending data

C. Green light is always on: The communication RS485 line connected to DATA+ and DATA- is reversed or the wiring is broken.

3.Reset switch in the upper left corner of the module

A.When the communication parameters (module address, baud rate, parity bit) do not know or communication parameters set by mistake, can not communicate with the module to establish contact, the solution is to reset the communication parameters;we use a crank pin to press the reset switch does not release, 5 seconds after the module [POW/SET] red light, release the reset switch, the communication parameters have been reset, as long as the module power off and restart The communication parameters of the module have been reset at this time.

B. Communication parameters after reset: address: 1, baud rate: 9600bps, parity bit: none.4.
